Clonezilla/DRBL on Ubuntu
I’ve talked about Clonezilla as a remarkably good an fast disk cloning utility previously, but there’s more to the clonezilla project than just rescue imaging of drives. There’s also a thin-boot server as well…. (diskless remote boot loader?) Anyway, This tutorial talks about how to setup clonezilla/drbl on a recent ubuntu install.
Of course, there’s no need to install the drbl server to a machine if all you intend to do is save disk images to it. Clonezilla supports copying disk images over the network through a variety of storage protocols.
